Timing tank limits

New guy and am planning a 40 day trip with wife, 10y/o and 6y/o. Either going to buy a used Class A or C around 30 feet so I think the tanks should be about similar. I understand there could be modified and blah blah blah. I am just wondering on average use, with live aboard conditions, but out most of the day. I have my route and destinations, now I just need to start planning logistics. How often should I plan on emptying my tanks and freshening them up? I am sure this is here somewhere. I looked for older posts, but really don't even know what this would be called. The words I was looking up gave me far too broad of a search. And "Phread's poop sheets" didn't go anywhere. I was really looking forward to whatever that was!

What you're asking is an extreme variable, it all depends on how you camp, with/without hookups, if without is there a dump station nearby, have you & your family learned water conservation,(extremely important), also, don't forget, you can always add more water, (by various methods), BUT all that water gets divided between the black & grey tanks. My wife & I can go about 7 days with a little effort.
